신발을 착용하다.

The word '신발' (sinbal) refers to 'shoes' or 'footwear'. It is a compound word formed from '신다' (sinda), meaning 'to wear (on feet)', and '발' (bal), meaning 'foot'. The verb '착용하다' (chagyonghada) means 'to wear' or 'to put on', and it is often used for items like clothing, glasses, or accessories. It is a more formal term than '신다' when referring to footwear. So, '신발을 착용하다' literally translates to 'to wear footwear' or 'to put on footwear'. The usage of '을/를' (eul/reul) is the object particle, indicating '신발' is the object being worn. The origin of '신다' dates back to Old Korean, and its root can be found in various forms throughout the history of the Korean language, consistently meaning the act of putting something on one's feet. The word '발' also has ancient roots, referring to the foot. '착용하다' is a Sino-Korean word, with '착' (着) meaning 'to wear' and '용' (用) meaning 'to use'. This combination gives it a slightly more formal or official nuance compared to purely native Korean verbs. The structure of 'Noun + 을/를 + Verb' is a fundamental grammatical pattern in Korean, indicating the object of an action. Therefore, '신발을 착용하다' is a grammatically complete and commonly used phrase in modern Korean.
